The low down on Pinhole Glasses
I don’t know about you, but sitting all day on the computer starring at the screen make me worry that my eyes are going to get worse than they already are!
I recently received an email from a guy at Pinhole Glasses Direct and was asked if I would like to take a look at the product and write about it. The concept behind these glasses has been interesting me for a while so I thought I would take a look.

What are Pinhole Glasses and how do they work?
As you can see from the image they are basically a pair of glasses with opaque plastic lenses full of little pin holes. You may be wondering what good that does? Wikipedia says that:
“Similar to the workings of a pinhole camera, each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. In eyes with refractive error, the result is often a clearer image. Unlike conventional prescription glasses, pinhole glasses produce a clear image without the pincushion effect around the edges.”
I’m sure that over time, if you wear eye correctional lenses of some form, that your eye sight has gotten worse… I know mine has, so the interest to me about these glasses is that they may actually strengthen my eyes and allow me to slightly reverse or freeze my prescription. They are also claimed to increase depth of field and create no distortion of the image that you see (unlike regular convex lenses).
They can be worn for most tasks that do not require a large peripheral vision such as reading or using the computer and if you are not afraid of what you look like you could use them at work and in your everyday life. Personally I could not see myself wearing them anywhere other than at home! The Pinhole Glasses Direct website has further information on how pin hole can be worn in place of prescription glasses and how they could benefit you.
Cons of Pinhole Glasses
- They are not recommended for people with over 6 diopters of myopia;
- They reduce brightness;
- They reduce peripheral vision;
- Wearing them in public may get you some strange looks! (This may be a pro for some attention seekers).
The Pinhole Glasses Direct website provides some interesting reads to learn further about this product. In their article The Science behind Pinhole Glasses they talk about the use of pinholes in the past and mention such interesting things as the Eskimos adaptation of the technology.
They are pretty well priced at only $19.99 a pair or $29.99 for two.
Have you ever used pinhole eyeglasses and if so, what did they do for you?

WoW. I’ve never heard of such a thing. I wouldn’t mind trying some on, just to see the effects. But yeah, I would definitely make fun of anyone wearing them in public :p

I think they’d be great for wearing at home, when reading or on the computer. You posted a great photo of the glasses, the website doesn’t show them off too well.
